Thomas had surgery to repair a torn labrum in his left shoulder during the offseason and was in uniform but just a spectator when the Seahawks opened training camp Friday.

Seattle coach Pete Carroll said the team is going to be patient in bringing Thomas back and would wait until it's "safe and secure" for Thomas to be on the field. Carroll would not give a timeline on Thomas' return.

Joining Thomas on the PUP list are defensive backs Jeremy Lane and Tharold Simon. Lane suffered serious arm and knee injuries in the Super Bowl, while Simon (shoulder) is hopeful of playing in the preseason. Paul Richardson (knee) is also on the PUP list.

Seattle placed defensive tackle Jesse Williams and defensive back Dion Bailey on the non-football injury list. Williams is recovering from surgery after being diagnosed with kidney cancer.
